Facebook PHP SDK - 将用户数据存储到MYSQL数据库中

Question

我完全不熟悉PHP和MySQL，但我在我的网站上实现了Facebook PHP SDK。目前为止一切正常，但我努力将用户数据添加到我的数据库（MySQL）。我拥有的一切都是一个数字，而不是用户名和oauth_uid（我得到了两个字段的数字5）。这是代码：

<?php 
    define('db_user','myUserName'); 
    define('db_password','myPassword'); 
    define('db_host','myHost'); 
    define('db_name','myDbName'); 

    // Connect to MySQL 
    $dbc = @mysql_connect (db_host, db_user, db_password) OR die ('Could not connect to MySQL: ' . mysql_error()); 
    // Select the correct database 
    mysql_select_db (db_name) OR die ('Could not select the database: ' . mysql_error()); 

    require 'lib/facebook.php'; 

    // Create our Application instance (replace this with your appId and secret). 
    $facebook = new Facebook(array(
    'appId' => 'MYAPPID', 
    'secret' => 'MYSECRET', 
     'cookie' => true)); 


    // Get User ID 
    $user = $facebook->getUser(); 

    // We may or may not have this data based on whether the user is logged in. 
    // 
    // If we have a $user id here, it means we know the user is logged into 
// Facebook, but we don't know if the access token is valid. An access 
// token is invalid if the user logged out of Facebook. 

    if ($user) { 
    try { 
    // Proceed knowing you have a logged in user who's authenticated. 
    $fbuid = $facebook->getUser(); 
    $user_profile = $facebook->api('/me'); 



     } catch (FacebookApiException $e) { 
     error_log($e); 
     $user = null; 
     } 
     }else{ 
     header('Location: index.php'); 

     } 
      $query = mysql_query("SELECT * FROM users WHERE oauth_provider = 'facebook' AND  oauth_uid = ". $user['id']); 
      $result = mysql_fetch_array($query); 

     if(empty($result)){ 
      $query = mysql_query("INSERT INTO users (oauth_provider, oauth_uid, username)   VALUES ('facebook', {$user['id']}, '{$user['name']}')"); 
      $query = msyql_query("SELECT * FROM users WHERE id = " . mysql_insert_id()); 
      $result = mysql_fetch_array($query); 
      } 



     // Login or logout url will be needed depending on current user state. 
     if ($user) { 
     $paramsout = array('next'=>'http://www.mywebsite.com/test/logout.php'); 
     $logoutUrl = $facebook->getLogoutUrl($paramsout); 
     } 


     ?> 

上述页面被称为user_page.php，它是用户在登录后重定向到的位置。我试图将“数据库”代码移到index.php（用户进行登录），但到目前为止，所有的努力都没有成功。这是index.php文件的代码：

require 'lib/facebook.php'; 

// Create our Application instance (replace this with your appId and secret). 
    $facebook = new Facebook(array(
    'appId' => 'MYAPPID', 
    'secret' => 'MYSECRET', 
     'cookie' => true)); 


    // Get User ID 
    $user = $facebook->getUser(); 


    if ($user) { 
    try { 
     // Proceed knowing you have a logged in user who's authenticated. 
     $fbuid = $facebook->getUser(); 
     $user_profile = $facebook->api('/me'); 

     header('Location: user_page.php'); 

     } catch (FacebookApiException $e) { 
     error_log($e); 
    $user = null; 
    } 
    } 


    // Login or logout url will be needed depending on current user state. 
    if ($user) { 
     $logoutUrl = $facebook->getLogoutUrl(); 

    } else { 

     $loginUrl = $facebook->getLoginUrl(Array('scope'=> 'user_interests,user_activities,user_education_history,user_likes,user_about_me, user_birthday, user_groups, user_hometown, user_work_history, email', 
      'redirect_uri' => 'http://www.mywebpage.com/test/user_page.php') 
     ); 
      } 

      ?> 

UPDATE *问题修正（$ user_profile而不只是$ USER）：

$query = mysql_query("SELECT * FROM users WHERE oauth_provider = 'facebook' AND oauth_uid = ". $user_profile['id']); 
    $result = mysql_fetch_array($query); 

    if(empty($result)){ 
    $query = mysql_query("INSERT INTO users (oauth_provider, oauth_uid, username) VALUES ('facebook', {$user_profile['id']}, '{$user_profile['name']}')"); 
    $query = msyql_query("SELECT * FROM users WHERE id = " . mysql_insert_id()); 
    $result = mysql_fetch_array($query); 
    } 

Answer 1

Facebook的用户在你的代码的数据存储在$user_profile而不是$user。
